It's past time to stop. And it's simultaneously too late. Magic is everywhere, there will be defectors against any coordination, and all the clever targeting in the world won't make there be more world.

Cor gives all his savings to a project that's trying to eat away the distance to the Moon, and he gathers supplies and tries something else.

A young human man in nothing but a pair of shorts, painted all over in broad patterns with still-wet blood and fine ash, appears on his knees in the middle of an unreasonably pretty city and falls unconscious.

"So can I, I just don't want to do unnecessary magic, also please stop vaguely hitting on me if you're doing that, aforementioned trauma. Look, if you're not accidentally going to chant something the wrong number of times you don't need me."

"I can land you nearish a point. The spell doesn't have great aim but you can fly, you'll be able to find it, they're hard to miss. You stare at it - which is kind of unpleasant - and whenever you're about to look away you say 'I am a force of destruction', and then you can look away for a second, till you've done that fifteen times. Might take you longer than a human if you have better tolerance for looking at disappearance points. Then you walk around it - flying over it should be fine too - and do the same thing from the other side, then you go a quarter of the way around clockwise, same thing, then from the opposite side from there. You go back to your starting point, you - there's some ash, in these little camp things, not that far from each point, you should take some of that, at home you'd normally just bring your own - go back to your starting point, throw in some ash, say 'I invoke the concept of fire' -"

"- whereupon the disappearance point should be pleasant enough to look at and then you'll be able to do the spell back here. I can come get you if you're not back by tomorrow? Not like you're going to freeze."

He heads sheepward. You warned all the existing mages, right? I'm going to try to land it directly in a point and if I don't manage that it'll waste a while and then be stuck unless it manages to figure it out.
